Electric Motor Design and Analysis

The introduction of power thyristors and rectifiers in dc-dc chopper and ac-dc converter circuits allows the replacement of the traditional dc series motor by the separately excited dc motor. This paper will consider the characteristics and the application of separately excited dc motors operating from either a dc input with a dc chopper using dynamic braking, or from a single-phase ac input with an ac-dc converter using regenerative braking, part I deals with the separately excited dc traction motor itself, while part II deals with its applications.
